Abstract (en)

[origin: EP2977176A1] A linkage of mould opening and closing and bottom mould positioning is provided in the invention, and the linkage is mounted on a bottle blowing machine. The linkage comprises a mould opening and closing assembly and a bottom mould positioning assembly for positioning the bottom mould relative to the machine frame of the bottle blowing machine. The mould opening and closing assembly comprises a bottom mould movable relative to a machine frame in up-down direction, a fixed mould plate and a moving mould plate. The bottom mould positioning assembly comprises a plurality of sliding blocks slidably disposed on the machine frame, multiple swing members swingably disposed on the machine frame for driving the sliding of the plurality of sliding blocks and a rotation member rotatable relative to the machine frame for driving the swinging of the swing members during its' rotation. The moving mould plate and the rotation member are fixedly connected with a rotation shaft which rotates around an axis of rotation. In the mould closing state, the moving mould plate is engaged with the fixed mould plate, the plurality of sliding blocks are inserted between the bottom mould and the machine frame and contact against the bottom mould. In mould opening state, the sliding blocks are detached from the bottom mould. The moving mould plate and the rotation member are driven by the rotation shaft to rotate, and the rotation of the rotation member is converted into the sliding of the sliding blocks, thereby achieving the linkage of the mould opening and closing and bottom mould positioning.
